I have the EMD springs as well on my 2015 GTI S with DSG. I decided to install the reverse rake pads, but not until after I installed a hitch on the back of my car. The added weight of the hitch, bike rack, and bike was making the rear squat just a bit too much. With the pads, it's pretty level now when loaded and not too raked without the bike rack and bike.
P.s. I'm originally from northwestern PA, but didn't want to deal with Winter anymore haha.
